The Vibration Analysis and Improvements of Nitrogen Reciprocating Compressor and Pipeline

Abstract:

Excessive vibration was observed from nitrogen reciprocating compressor buffer tanks and pipelines since the operation of this unit started in a coal chemical plant. Welding points had been frequently cracked on bolt buffer tanks, pipelines and bolts, which often led to a delivery failure of coal for subsequent reaction, causing great economic losses. In order to identify the root cause of vibration, a comprehensive analysis on the reciprocating compressor and pipeline system was conducted. The vibration has been kept within an acceptable range after the adjustment. The total production in the factory has been increased with effectively controlled cost and energy consumption. The probability of production system shutdown and accident is also significantly reduced.
